Abstract (en)
[origin: US2005032032A1] A biomass generator useful for continuously growing and withdrawing bacteria to be used in a desired beneficial application, the generator having a bacteria growth chamber; water and nutrient inlet ports; upper and lower outlet ports; a recirculating pump withdrawing and reintroducing fluid to establish a vortex in the growth chamber while controlling foaming and pump cavitation; a low pressure air inlet line discharging air inside the growth chamber above the vortex; a fluid discharge line receiving bacteria-containing fluid from the upper outlet port of the growth chamber; a flush line discharging wash water into the fluid discharge line; and an electrical controller cooperating with solenoid-operated valves and a feeder mechanism to periodically introduce water and nutrients into the chamber, thereby simultaneously causing bacteria-containing fluid to be discharged from the growth chamber through the upper outlet port. A method for growing bacteria using the subject apparatus is also disclosed.
